So does this mean that 2ns party - direct-contact heatpipe cooler's are useless ?
Lastly , are the above cooler's same as "air-coolers"

His assumption is that the CPU die area will only be as big as the black square portion in the image. So the other 2 heatpipes in the side aren't making direct contact with the CPU die.
Yes direct contact heatpipes are also used in air coolers.
